In this lab, we have tested Load Balancing of PE routers according to Vrfs.
PE-1 and PE-2 routers were in the same POP.PE-3 was at the remote POP.PE-1 router is also
Route-Reflector(it is bad design for real world) of all routers.

test
test2
For test vrf2, traffic should pass through PE-1
For test vrf, traffic should pass through PE-2
We have configured HSRP to provide loadbalancing and redundancy for incoming traffic to Provider network from the customer.For test vrf`s interface, PE-2 router was active; for test2 vrf`s interface PE-1 router was active.
We have increased weight on PE-1 router (which is also route-reflector) for incoming traffic from other POPs through Mpls backbone.
Here is the configurations:
